Russian Strikes on Kyiv Data Centers Disrupt Operations at Several Ukrainian Media Outlets and Affect 100000 Households

BLUFRussia's deliberate targeting of shared data-center nodes in Kyiv converts single strikes into cascading outages across media, telecom, and households, exploiting concentration risk Ukraine has not yet mitigated.

A Russian strike on the Dc|Cosmonova data center in Kyiv knocked the facility's core network and backbone offline on September 26, the second hit on the site in two days, after Cosmonova reported the first strike on the evening of September 25 12. Cosmonova said all staff were safe and that it was restoring services from backup sites, while access to the facility remained partially restricted by authorities 12. The same morning, internet provider Kolo.TV reported its third strike in recent days, taking down its website, chat support, and phone lines while engineers rerouted traffic to backup systems 23. Broadcasters Novyny.Live and Armiia TV suspended operations, and public broadcaster Suspilne said its video players failed because they run on Cosmonova's infrastructure 14. The Digital Transformation Ministry said a September 23 strike on a separate Kyiv data center had already cut internet access for roughly 100,000 households in the capital and surrounding region 4.

Analysis
Russia is targeting shared data-center infrastructure rather than individual broadcasters, so destroying one facility cascades into outages across unrelated media outlets, ISPs, and households simultaneously. The September 27 mass strike wave, which included the second hit on Cosmonova within two days, situates the data-center strikes within a broader campaign of 170 drones and glide bombs in a single 24-hour period. Cosmonova's assessment that its damaged facility will no longer operate signals forced client migration and prolonged service gaps for firms lacking independent backup capacity. The Digital Transformation Ministry's confirmation that a single September 23 strike cut internet access for roughly 100,000 households exposes Kyiv's telecom resilience as dependent on a small number of physically concentrated sites.
